For medium high-income countries banks, they get the diversification effect to reduce the risk of bank non-performing loans deposited. Medium low-income countries banks which demonstrate the result was increase the insolvency risk, so with the lower income levels, income diversification will be adversely affected. The results show that income diversification for the Eastern Europe banks can significantly reduce the risk of bank non-performing loans deposited, and reduce the insolvency risk. The East Asia banks are showing significant reduction volatility of asset returns. Latin America is showing negative effect, significantly increase the insolvency risk.
